Facing a number of charges stemming from a fatal crash in Nashville last Friday, 3 Doors Down bassist Robert Todd Harrell has checked into a rehab facility.

According to the Associated Press, Harrell's lawyer confirmed that the 41-year-old musician went directly to a drug treatment facility after [article id="1706150"]posting $100,000 bond[/article] on Tuesday in the case.

"He was released on bond and immediately went and checked himself into treatment," said Nashville criminal defense lawyer Ed Ryan. While Ryan would not name the facility, he said the rehab was not court-ordered and that Harrell went voluntarily. Harrell landed in jail after an [article id="1706097"]incident[/article] on Friday night when his Cadillac CTS was traveling at a high rate of speed on the interstate and clipped the bumper of a pickup truck, sending it swerving out of control and down an embankment, where it flipped over. The driver, 47-year-old Paul Howard Shoulders Jr., was killed after being ejected from his truck.

Police said Harrell showed signs of impairment at the scene and admitted to drinking some hard cider earlier and taking the prescription painkiller Lortab and anxiety drug Xanax. He was transported to Nashville's Metro Jail and was later also accused of bringing controlled substances into the jail when deputies found a plastic baggie hidden in his sock with eight additional Xanax pills, 24 Oxycodone pills and four Oxymorphone pills.

Harrell admitted to being under the influence and is now facing a number of charges, including vehicular homicide by intoxication, unlawful possession of a controlled substance, violation of the implied consent law and possession of contraband.

The "Kryptonite" group issued a statement expressing their condolences. "We are deeply saddened by the passing of Paul Howard Shoulders, Jr. Our hearts and prayers go out to his family and friends at this difficult time." On Monday, they released a second statement announcing that, "Out of respect to Paul Howard Shoulders, Jr., and his family, 3 Doors Down has cancelled the band's four scheduled U.S. April/May appearances." According to their official site, the band had two dates scheduled in late April and early May. Current plans call for them to resume touring on May 31 in Moscow before returning to the U.S. for scheduled dates in July co-headlining alongside Daughtry. It was unknown at press time if Harrell would be joining them for the upcoming shows.
